I just tried my new AXE that was replaced under warranty. So far so good. We are getting a major rain storm right now so I can't go outside. I have been hovering around in my garage. I only have about a 6' x 8' area, so I must be real careful. While I was waiting for my AXE to be replaced I aquired a Blade CP Pro and have been flying that. I like the Blade better than the AXE. The blade is more sensitive but seems to be more stable. The Axe is stronger though. The real test will be when I can get out side and have more room to play in.
